Creating a Rest

You can use Rest to remove material from the active body to create a platform-like area. The area of the rest is an inner protected volume, which means that no other volumes within the same body can penetrate this area.

You can add a rest to a shelled or unshelled body. The results will vary, depending on the selected volume type. If you add a rest to a shelled body, it creates supporting walls, if necessary.

Note: Depending on your role, you may not have access to this functionality.

Using the Display Only Parents Option to Retrieve a Creation Context
  1. From the Create section of the action bar, click Rest .

    The Rest.x dialog box appears.

  2. Select a closed profile.

    A rest requires a closed profile on the body indicating where the rest is to be created.

    Tip: If no profile is defined, click Positioned Sketch to sketch the profile you need.

  3. Enter a value in the First length box to define the distance from the sketch plane up to the bottom.
  4. Enter a value in the Second length box to define the distance from the sketch plane up to the landing. In a preview, the rest is displayed in red as it is a protected area.


  5. Click Mirrored extent to extrude the profile in the opposite direction using the same length value as the one defined for the first length.
  6. Click Reverse direction or the arrow in the work area to reverse the extrusion direction.

    By default, the direction is normal to the profile, meaning that the profile is extruded normal to the sketch plane, to specify another direction, in the Direction box, select a geometrical element to be used as the new reference.

  7. Select the Draft tab to define a draft angle.
  8. From the Draft behaviour list, select Intrinsic to feature.
  9. Enter the desired value in the Angle box.

    The default neutral element (defines a neutral curve on which the drafted face will lie) is the Profile plane. The other possible neutral elements can be:

    • Bottom
    • Landing
    • Plane/Surface.

    A Clearance volume angle box and a Reverse button allows the clearance draft to be independent of the platform draft. This allows, for example, the platform draft to be used for aesthetic reasons (large draft value) and the clearance draft to be used for manufacturability (small draft value).

  10. Enter values in the Angle and in Clearance volume angle boxes.
  11. Click next to Angle and Clearance Volume Angle.


  12. Click the Fillet tab.
    Selecting Lateral radius check box enables you to fillet lateral edges. Then, you need to set the radius value of your choice. Select the Bottom radius check box to fillet bottom edges.
    Important: You can select the Draft fillets check box from the Fillet tab. For more information, see Draft Fillets.
  13. Select the Landing radius check box to fillet landing edges and enter a radius value.


    If the rest is to be shelled, you can select Constant wall thickness check box. This propagates the fillets into the shell, thus maintaining a constant wall thickness.

  14. To define the wall, you can set one of the two options available from the Type list:

    • Use body thickness: the rest wall thickness is that of the active shelled body.

    • Enter thickness: Enter the required value. After this option is selected, the value box becomes available. Wall thickness values can only by positive values.

    You can control whether the wall is constructed inside or outside of the selected profile. The default is an inside wall thickness.

  15. Click OK to confirm and create the rest.
    The rest is created. The protected area is hidden. Rest.x is added to the tree under the Solid Functional Set.x node.
